Hi I'd like to remove a load bearing wall. I'm aware of the permit process but can anyone advise exactly who will do the steel calculations? It's easy to find structural engineers in the UK but I don't know if this is the right person in Spain. They seem to be mainly civil engineers working on big projects.

Ask any local architect, they will know who you need to contact.

the town hall will also "have a list" and one on their payroll..
